You will never work as a full time employee. Ten to twenty hours a week are common. You will never get more than a .25 cent raise every 12 months. When you see your quarterly bonus check and then find out what your bosses get... you will feel very ill.
The longer you are there and learn various duties, you will be asked to start doing dept. head duties and the heavy hands will push to see how much you will do.... all without the chance of a raise of more than .20 -.25 cents a year. They will also dangle the coveted full time status in front of you like a carrot on a stick. Nobody ever gets the carrot. I saw multiple full time positions open up and they always replaced the lost full time hours with multiple part timers.
You will be used up until there is no more and then they will eventually find a way to make you want to leave. With the constant flow of new hires... you were never really anything but a number to them... a very small number.
You will be terminated if a customer is having a bad day and complains hard enough about you... doesn't matter how long you have been there and doesn't matter if you successfully help thousands of customers every month and have a perfect no write up history. They will take the word of the customer every time... they have too. That directive comes from above store level.
They will smile and lie to your face. Do yourself a favor... find another company to work for and save yourself the future stress.
